if your strapped for cash,stay away from nos..there is a lot of problems "undpredictables" with it.if you dont have much money how are you going to replace the motor when you blow it?if you do this.i would bullet proof your whole motor and that alone is a grand.good luck but with how much that zex costs you could drop in a zc motor,and that in my opinion is a hell of a lot better than using the juice.
